SoftMaker Office 2016 is a good alternative for a reasonable price
Have you tried out SoftMaker Office 2016? It's available for less than one third of the price of Microsoft Office 2016 Home & Business, but includes 3 licenses instead of one, plus regular updates and free technical support.
My experiences are very positive since I use it. It includes TextMaker (word processing), Presentations (presentation builder) and PlanMaker (spreadsheet) which open and save Word (doc/x), Excel (xls/x) and PowerPoint (ppt/x) files generally without a glitch - data transfer is excellent, never had any problems going back and forth. Additionally, SoftMaker Office 2016 includes an enhanced version of Thunderbird for e-mails and tasks, and a macro language called BasicMaker.
The range of features is comparable to Microsoft Office, you won't miss anything. ZThe user interface is similar to that of Microsoft Office 2003 (good old menus, no ribbons), but looks friendlier and has several modern extensions included. I prefer it over ribbons.
